In this paper, we reported a copper-catalyzed ring-opening reaction of arylcyclopropanes by N-fluorobenzenesulfonimide, leading to N-allylsulfonamides in moderate to good yields. This procedure tolerated bromo, fluoro, trifluoromethyl, phenyl and alkyl groups in the phenyl, proceeding with a sequential ring-opening of arylcyclopropanes, and copper-mediated β-H elimination of alkyl radical.
在本文中,我们报道了铜催化的芳基环丙烷与N-氟苯磺酰亚胺的开环反应,以中等至良好的收率生成N-烯丙基磺酰胺。该过程容许溴、氟、三氟甲基、苯基和苯基中的烷基,进行芳基环丙烷的连续开环,以及铜介导的烷基自由基的β-H消除。
